sounds like you need a tech.
Possible UBR problem. ( Green Box outside house or flat)
to be safe , make sure all conections to your modem are tight and secure, and the cable from the ground outside into your house/flat is tight.
Ask neighbours if they are on VM and see if they are having the same issues.
Ring Vm on 150 (vm fone) Or 0845 454 1111 from any other fone Line.
